Responses of Water and Pigments Status, Dry Matter Partitioning, Seed Production, and Traits of Yield and Quality to Foliar Application of GA3 in Mungbean (Vigna radiata L.)

This study evaluated the role of gibberellic acid [GA 3 ; (0, 100, 200, and 300 ppm)] in modulation growth, physiology, yield, quality traits two varieties (BARI Mung-6 BARI Mung-8) mungbean ( Vigna radiata L.). Irrespective Mung-8), ppm GA differentially modulated tested parameters (relative water content, RWC; photosynthetic pigments: chlorophyll a, b, carotenoids; growth parameters: fresh dry weights leaves, petioles, stems, roots; yield contributing such as plant height, number pods ?1 , grains pod length, 100-grain weight; grain nitrogen protein). However, compared to lowest (100 ppm) highest (300 ppm), moderate concentration (200 led values leaf-RWC, where this parameter exhibited 16.1 13.4% increase Mung-8 Mung-6, respectively. Similarly, herein significantly increased up foliar application thereafter these decreased with . The 200 ppm-led changes were higher when Mung-6. Considering traits, positively influenced protein content grains, increases 25.2% N, 17.7% over control Mung-6; whereas, 28.3% 18.3% control. Overall, responded supply Hence, order high may be applied V. before during flowering. major mechanisms underlying responses relation, concentrations need explored.
